Abstract

L'invention concerne un appareil permettant de détecter un analyte dans un fluide. L'appareil contient un dispositif de collecte de fluide configuré pour recueillir le fluide contenant l'analyte ; une entrée de fluide en communication fluide avec le dispositif de collecte de fluide configurée pour injecter le fluide contenant l'analyte dans le dispositif de collecte de fluide, un agent d'interaction d'analyte en communication fluide avec le dispositif de collecte de fluide, caractérisé en ce que l'agent d'interaction d'analyte, une fois en contact avec l'analyte, réagit pour provoquer un premier changement d'énergie thermique dans le dispositif de collecte de fluide ; un modulateur provoquant un second changement d'énergie thermique ; et un dispositif de détection thermique. Des régulations de débit sont incluses dans divers modes de réalisation. Le dispositif de détection thermique dans certains modes de réalisation comporte au moins un dispositif pyroélectrique. L'invention concerne également des procédés englobant le traitement de signaux générés par le dispositif.
